Building the Armory Bitcoin client for the Raspberry Pi

This is how I got Armory (etotheipi/BitcoinArmory; http://bitcoinarmory.com/) cross-compiled for the Raspberry Pi.

This is a great way to keep an air-gapped offline wallet for only $30 dollars for the RPi (that you can also use for other things; experiment, it's awesome) and $7 for a Class 10 4GB SD card, really easy to keep in a safe and secret place.

Dependencies

On my Ubuntu box, I had to apt-get install these packages. Your mileage may vary.

bison flex texinfo libtool automake libncurses5-dev gperf python-pyopencl git-core build-essential pyqt4-dev-tools swig libqtcore4 libqt4-dev python-qt4 python-dev python-twisted

The cross-compiling toolbox

Chris Boot has an awesome post on how to setup a cross-compiler for the RPi, follow it:

http://www.bootc.net/archives/2012/05/26/how-to-build-a-cross-compiler-for-your-raspberry-pi/

But note that during the menuconfig you have to go into C-compiler → Additional supported languages and enable C++.

If you want, you can skip steps 2 to 14 (the whole menuconfig) of the second block by placing the .config file attached to this gist into the folder where you run ct-ng.

BUILD IT!

Now that you have your arm-unknown-linux-gnueabi-g++ working in your $PATH, clone the Armory repo

git clone git://github.com/etotheipi/BitcoinArmory.git
cd BitcoinArmory

Apply the attached patch to the two Makefiles (a smarter patch might be merged in the repo in the future)

patch -p1 < CXX.patch

And MAKE

CXX=arm-unknown-linux-gnueabi-g++ make

Finally, create a tarball to move to your shiny Raspberry

mkdir -p BitcoinArmoryRPi/img/
cp *.py *.so README LICENSE BitcoinArmoryRPi/
cp img/* BitcoinArmoryRPi/img/
tar cvfz BitcoinArmoryRPi.tar.gz BitcoinArmoryRPi

That's all folks!

Thanks for the great tutorial. Is there any specific version of Armory you did this for? With the latest one of the git repo (2013-01-15), I got stuck at the following. Any ideas? Cheers,

I get all the way to the step where I need to apply the CXX.patch file, then I get this error. I'm using the latest version as of 2013-03-11. Can you help me out, please?
